Jose Mourinho has named Ronaldo Nazario as the greatest player of all-time.

Having enjoyed a glittering managerial career, which has seen him take charge of Chelsea , Inter Milan , Real Madrid and Manchester United , Mourinho knows a thing or two about talented footballers.

“Ronaldo, El Fenomeno, Cristiano Ronaldo and Leo Messi have had longer careers, they have remained at the top every day for 15 years," Mourinho told LiveScore .

“However, if we are talking strictly about talent and skill, nobody surpasses Ronaldo [Nazario]. When he was at Barcelona with Bobby Robson , I realised that he was the best player I'd ever seen take to the field.

“Injuries killed a career that could have been even more incredible, but the talent that that 19-year-old boy had was something incredible."
